Study on the Spatio-Temporal Changes of Precipitation in Loess Plateau from 1959 to 2018
Published 2025-06-01“…Precipitation plays a critical role in the Earth's hydrological and energy cycles, significantly influencing the biogeochemical cycles and energy exchanges on the land surface.In the ecologically fragile region of the Loess Plateau, the spatial and temporal variability of precipitation has profound implications for both the ecological environment and socioeconomic development.Therefore, study on the spatial and temporal variations of precipitation in the Loess Plateau holds substantial theoretical and practical significance.This study utilizes daily precipitation data from 115 meteorological stations across the Loess Plateau and its surrounding areas, covering the period from 1959 to 2018.By employing methods such as Inverse Distance Weighting (IDW) interpolation and wavelet analysis, the study provides a comprehensive analysis of the spatial and temporal characteristics of precipitation over the past 60 years in the Loess Plateau.The results showed that: (1) The spatial distribution of precipitation in the Loess Plateau exhibits a clear "stepped" pattern, gradually decreasing from southeast to northwest.This distribution highlights a significant gradient where the southeastern regions receive more precipitation than the northwestern regions, with a similar trend of more rainfall in the south compared to the north.Furthermore, localized topography plays a crucial role in modulating precipitation, with higher elevations generally receiving more rainfall.(2) Under the influence of changes in the East Asian monsoon and atmospheric circulation patterns, the spatial distribution of precipitation from 1989 to 2018 differs significantly from that of 1959 to 1988.Specifically, the 200mm and 400mm isohyets have shifted northward, with a notable decrease in precipitation in the southeastern monsoon-dominated areas, while precipitation has increased in the non-monsoon northwestern areas.The monsoon marginal zone of the Loess Plateau is particularly sensitive to monsoon variability.The continuous weakening of the East Asian summer monsoon has diminished the capacity for moisture transport, further exacerbated by El Niño-Southern Oscillation (ENSO) warm events, both of which have contributed to reduced precipitation in the southeast.Conversely, changes in atmospheric circulation have led to increased precipitation in the northwest, resulting in a slight expansion of the semi-humid regions in the area.(3) Over the study period, precipitation in the Loess Plateau exhibits a fluctuating upward trend, indicative of a general tendency towards increased wetness in the region.This suggests a long-term shift towards more humid conditions, which could have significant implications for the region's ecological restoration and water resource management.(4) The interannual variability of precipitation in the Loess Plateau is characterized by oscillations on multiple time scales, specifically at 5-year, 7-year, 11-year, and 43~45-year intervals, with the 5-year cycle identified as the dominant periodicity.…”

An inverse probability weighting method for estimating the net benefit in survival analyses in observational studies
Published 2018-12-01“…Background: Recently, in the context of randomized trials, a measure on the difference scale called the net benefit was developed for survival analysis. As this measure does not require the assumption of proportional hazards, it is an attractive new measure of the treatment effect to apply instead of the hazard ratio calculated under this assumption. …”
